Shingles Healing: Recognizing Signs of Recovery

Herpes zoster (shingles) typically resolves in 2–4 weeks. Healing signs:

1. Pain Reduction: Burning, neuropathic pain diminishes in intensity and frequency.
2. Blister Crusting: Vesicles dry, form honey-colored crusts (day 7–10).
3. Desquamation: Crusts slough off; new pink skin underneath.
4. Rash Fading: Erythema fades from red → brown/pink → normal skin tone.
5. Decreased Sensitivity: Allodynia/hyperesthesia improves.
6. Post-Herpetic Neuralgia (PHN) Risk: Persistent pain >90 days after rash onset occurs in ~10–18% (higher with age). Early antiviral (within 72 hrs) reduces PHN risk.

When to Follow Up

• Rash not improving by 2–3 weeks.
• Signs of bacterial superinfection (increasing redness, warmth, pus, fever).
• Ophthalmic involvement (Hutchinson's sign) – emergency.
• New neurologic deficits.
